## 统计代写|数据可视化代写Data visualization代考|Visualizing Time and Space

The three decades from 1950 to 1980 were a period of active growth in the development and use of increasingly realistic data visualization. One thread concerned statistical and computational: dimension-reduction methods for representing high-D data in a low-D space that could be plotted, mostly in 2D. ${ }^1$ Another thread in this period reflected new graphical methods, boosted by increasing computing power, which allowed graphic displays to become increasingly dynamic and interactive. Such displays were capable of showing changes over time with animation, thus changing the nature of a graph from a static image to one that a viewer can directly manipulate, zoom, or query. In these ways, the escape from Flatland continued as a wide range of important problems were illuminated by new approaches to understanding data in higher dimensions.

Once again, these developments illustrate the interplay between advances in technology (computer display and software engineering) and scientific questions for which visualization methods held promise. Today, we see the impact of this in the work of data journalists who now routinely present the details behind important stories (the Brexit vote in the United Kingdom, climate change, COVID-19, etc.) in high-impact online, interactive graphic applications. This chapter traces the origins of these ideas and some of the scientific questions that prompted this evolution of visualizing motion, time and space.

There is, in nature, perhaps nothing older than motion, concerning which the books written by philosophers are neither few nor small; nevertheless I have discovered by experiment some properties of it which are worth knowing and which have not hitherto been either observed or demonstrated.

Galileo’s seventeenth-century observations foreshadow the origins of the cinema, computer-animated films, and-most relevant to this narrativedynamic data graphics. The popularity of modern dynamic data displays can be traced to scientific questions about the nature of human and animal motion. As technology developed, the study of motion and its visualization branched out from a pleasurable pastime to the huge industries of Hollywood and Netflix while also having important scientific applications in aerodynamics (the wind tunnel), medical imaging (blood flow in the heart and brain), and ecology (migratory patterns of animal species) among others

Aristotle’s De Motu Animalium (The Movement of Animals) was the first book setting out the principles of animal locomotion. Nichole Oresme’s 1360 “pipes” diagram (see Figure 2.2) was intended to show some possible mathematical relations between time and distance traveled. Around 1517, Leonardo da Vinci drew detailed anatomical studies of moving cats, horses, and dragons; Galileo later conducted experiments on motion and gravity between 1633 and 1642. However, the modern interest in these questions arose in the late 1800 s when new technologies for recording could provide new insights.
To a physicist, motion is nothing more interesting than a change in position over time. It can be reduced to simple, but elegant, equations giving velocity (the first derivative) and acceleration (the second derivative). A velocity, $v$, of a horse galloping at $45 \mathrm{mph}$ can be reduced to the equation $v=d x / d t=45$. The acceleration, $g$, due to gravity on Earth can very nearly be reduced to a constant, $^2 g=9.8 \mathrm{~m} / \mathrm{s}^2$, or $32 \mathrm{ft} / \mathrm{s}^2$.
